From 8c63b6897daef9ce771262a8075abb98b6d40da8 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 28 Oct 2002 05:30:46 +0000 Subject: Change MachineBasicBlock's to not be Annotations, instead they are kept as part of a linked list tracked by MachineFunction. MachineBasicBlock::get is now linear time instead of constant time, and thus is deprecated! llvm-svn: 4337 --- llvm/lib/CodeGen/MachineFunction.cpp | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'llvm/lib/CodeGen/MachineFunction.cpp') diff --git a/llvm/lib/CodeGen/MachineFunction.cpp b/llvm/lib/CodeGen/MachineFunction.cpp index b9c017a..15036a4 100644 --- a/llvm/lib/CodeGen/MachineFunction.cpp +++ b/llvm/lib/CodeGen/MachineFunction.cpp @@ -72,6 +72,21 @@ Pass *createMachineCodeDestructionPass() { } +// get - This deprecated static method returns the MachineBasicBlock object +// for the specified BasicBlock. +// +MachineBasicBlock& MachineBasicBlock::get(const BasicBlock *BB) { + const Function *F = BB->getParent(); + MachineFunction &MF = MachineFunction::get(F); + + for (MachineFunction::iterator I = MF.begin(), E = MF.end(); I != E; ++I) + if (I->getBasicBlock() == BB) + return *I; + assert(0 && "MachineBasicBlock object not found for specified block!"); + return get(BB); +} + + //===---------------------------------------------------------------------===// // MachineFunction implementation //===---------------------------------------------------------------------===// -- cgit v1.1
